Useful for Practicing Weak Areas!

What I like about GMAT Club Tests was that the questionbank made it quite easy for me to focus only on the area of questions that I had trouble with. Not only that, you could participate and read past discussions on all available questions just in case you need to know where you went wrong. Generally speaking, these was all high quality questions that were quite close to the actual questions you could get on the test. Only issue for me was that the CAT tests available use the same set of questions as the question bank. So if you've done a majority of questions form the Questionbank, you couldn't attempt a CAT unless you reset the questionpool (mark all solved questions as "not attempted yet"). Other than that, I found the tool extremely useful for practicing weak areas!
